To allwhm it'mag concern.- Be it known that 1, JOHN C. GIBBS, a citizen of the United States, residing in the city and ,county of Lancaster, State of Pennsylvania, have invented a new and useful Ice- Cream Freezer, ofwhich the following is a specification.

My invention consists of improvements in an ice creamfreezer as will be hereinafterv claims. 7

The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof may be varied, and so it'is to be understood that the invention is not limited to the specific details shown and described, as long as they are within the spirit and scope of the claims.

Figure 1 represents a top or plan view of [an ice cream freezer embodying my invention.

Fig. 2 represents a central vertical section on line 2-2 of Fig. 1.

Fig. 3 represents a horizontal section of a portion on line 3-3 of Fig. 2.

' Fig. 4 represents a top plan view of aportion of the can of the freezer.

Fig. 5 represents a bottom plan of the 1.,bridge orcover-piece of the ice-tub.

Fig. 6 represents a vertical section of a detached portion.

Similar numerals of reference lndlcate correslpofnding parts in the figures.

eferring to the drawings, 1 designates the can of the. freezer, and 2 designates the dasher therein, and 3 designates the tub or pail, which members exceptingthe features construction."

of my invention applied thereto are of usual The can is mounted on the step 4 on the bottom of the tub whereby said can may be rotatedthereon. 'The dasher is mounted on the step5 on the bottom of the can whereby it is supported thereon, it being understood that the canrevolves around the'dasher and l the latter will be held stationary by means as will be hereinafter described.

' 6 designates the cover of the can,'the same having on'the top thereof centrally thereon the pinion? in'which is a vertically arranged circular opening or bore 8, the latter being in-communication with the circular opening 9in' the cover 6 of the can.

10 designates a bridge or cover-pieceduced.

ing 8 in the pinion 7 and consequently with the opening 9 in the cover 6 of the can.

Rising from the top of the dasher 2 is the tongue 14 which is passed through the openlng 9, the opening 8, and slot 13, said tongue being fiat in form, and said slot being similarly-shaped whereby, as the bridge isstatlonary and receives said tongue in said slot as has been stated, the dasher is held stationarily while the can rotates around the same.

15 designates a crank handle whose limb 16 1s mounted on the "bearing 17 on the bridge 10, passes through the latter and has on lts lower end which is below said bridge the spur Wheel 18 which entering the tub is adapted to engage the pinion 7.

The operation is as follows t The crank handle is operated whereby it lmparts rotation to the spur wheel and consequently to the pinion 7, thus rotating the can 1n which the ice cream mixture had been duly placed and the tube'suitably iced, the ice cream will be easilv and quickly pro- WVhen this is accomplished the bridge is unlocked and raised when the spur wheel 18 follows the same and so removed from the pinion 7 the bridge also clearing the tongue 14; Then the cover of the can may be removed when the contents of the can are accessible, for further action usual in such cases. r

The cover 6 is removably interlocked with the top of the can so that the latter will ro- "tate with said cover by means of the interengaging depressions 19 in thejsides of the can of the rim of the cover, as most plainly shown in Fig. 3. y

Securedto the under side of the bridge is the plate 20 in which is a slot 21 which registers with the-slot 13 and serves to reinforce said bridge about said slot 13, the walls of which latter are subjected to strain owing 'to their embracing action of the tongue 14 to hold the dasher stationary.

When the catch 12 is released and the bridge 10 raised it turning on its hinge 11,

the spur wheel 18, crank handle 15 and the is. y to operate'the latter by h the crank handle 15. v

A lo he ne the peculiar nanne he ed he k bridge sheet st f manu b g :is the thinner a 1 b PlfiWs I (r is obtained res I a. thorough vstirring; of

is done by fastening the pinion to a sheet metal upstanding rigid tubular member carried by the bridge-plate, this tubular member fitting the interior of the pinion. This not only firmly anchors the pinion to the can-to but also gives me the wide opening that I need for the flat dasher-tongue 14. This construction is especially advantageous and necessary where, as in the present case, it is desirable to reduce the expense of the freezer by using sheet steel of the thinner grades where the weight of the freezer is to be reduced to a minimum. In this way, I reduce the metal in the pinion to a minimum and also anchor it with sufiicient rigidity and permanence to withstand the comparatively great strain it is subjected to in operation.

I claim 1. In an ice cream freezer, an ice-can, a metal bridge-member having transverse slots, a metal journal-bracket mounted thereon and havin dependin limbs extending through said slots an bent laterally at their lower extremities, these laterally-bent lower extremities being fastened to the under side of the bridge-plate, a driving crank-shaft journaled in said journalbracket, and gearing connecting this shaft to the rotary element of the freezer.

2. In an ice cream freezer, a rotatable can, a dasher stationary therein, a tub, a bridge removably connectible with said tub and adapted to control said dasher against rotation, a gear wheel on the cover of said can secured thereto, a crank handle having a bearing. on said bridge, a gear wheel on said handle, said. gear wheel removably intermeshing with said pinion, and means on said bridge adapted to interlock the latter with said tub and retain said gear wheel and pinion in engagement, said bearing for I the crank handle consisting of a plate substantially arch-shaped having one limb of said crank handle mounted in the crown thereof and havin its leg portions mounted on said bridge an provided with laterally turned feet which are secured to the latter.

' 3. In an ice cream freezer, a can, a cover therefor, a dasher, a gear wheel on said cover, a movable bridge in said tub, a crank handle mounted on said bridge, a reinforcing plate on said bridge about the wall of the slot therein, and a gear wheel on said handle, said gear wheels being adapted to intermesh, said dasher having an upwardly extending fiat tongue, said gear wheel on said cover having a circular bore in which said flat tongue is received, said bridgehaving therein a slot, and said reinforcing plate having therein a slot, said slots conforming to said flat tongue and being in register with said bore.

I 4., In an ice cream freezer, a tub, a bridge thereon, a rotatable can, a stationary dasher in the latter, a pinion on the cover of said can, a tubular sleeve on the cover of the can, said pinion having a bore in its hub portion and fitted on and secured to said sleeve, a spur wheel on said bridge adapted to mesh with said pinion, an 11 wardly extending flat ton ue on said das er adapted to pass throng said cover, pinion and bridge, the latter having therein a slot adapted to receive said tongue and embrace the same, and a reinforcing plate on said bridge having therein a slot which is adapted to register with the slot in said bridge, both slots being adapted to register with said bore.

5. In an ice cream freezerembodying a rotary cream-can having a removable metal cover provided with a rigid upstanding central tubular member, a pinion surrounding this upstanding tubular member and fastened thereto, a dasher within the cream-can having a flat anchoring tongue extending up through said tubular member to thereb form two passages one at either side thereo and means for rotating said cream-can throu h the medium of said pinion.

6. in ice cream freezer embodying a cream-can having a circular central passage in its cover, a flat dasher in the cream-can having an anchoring tongue extending up through said passage, this anchoring tongue being flat. to thereby form two passages one at elther side thereof, means engaging the tongue at its upper end to anchor the dasher, and means for rotating the cream-can.

In testimony whereof I afiix my signature in presence of two Witnesses.
